Isnt design the same as build? Obviously not, as CoffeeCup has separate programs - so what is each used for?

Would you say it is better than MachForm HTML interactive form builder?

Hi Chris,
Form Designer has no backend scripts so it's only the design of the form. Form Builder designs and builds the back end scripts for you.
I've taken to Form Designer as I can do my own backend scripts and conditional controls. If you can't or don't want to do your own processing scripts I would use Form Builder. If you have Site Designer you can do everything Form Designer does while building the rest of your site. It all comes down to abilities and time. There are plenty of users on here to help if you get stuck.
